New Item Idea or Rework for Ohmwrecker

Hi first time posting here! English isn't my first language so hopefully there isn't a lot of grammatical errors while I try to explain this the best I can :D

I saw a reddit post which talked about a potential Ohmwrecker rework that disables shields. Well, tonight while I was sleeping, I had a dream where I visually saw the reworked Ohmwrecker in play. YES I DID DREAM THIS.

First I'll try to describe what I saw and then I'll describe the modified version of it I thought out to try and make it more balanced:

DISCLAIMER I only recall the ACTIVE of the item, I don't recall the stats of it like if it's a tank item or what but I would assume so.

• Dream Version: X Champion walked close to the enemy champions and activated the item. 1 champion(An ADC) was shielded(Janna Shield) and 2 others weren't(Janna and Maokai.) Once the item got activated, the 3 champions were covered in some sort of fire that dealt a certain amount of True Damage. It dealt enough to break the shield and enough to chunk those unshielded.

• Modified Version: X Champion walks towards 5 enemy champion, ALL lvl 13. The item has a radius(of like 500 or 700 range, whichever seems more balanced) and any champion that is inside that radius that has a shield on them will take a a certain amount of True Damage that scales at certain levels(6/11/16 or 4/8/12/16 or something else) or This item CANNOT be activated if there isn't at least 1 champion that is shielded. Xayah shielded by Janna(5pts into Shield) walks in the radius, Nautilus with his shield(5pts cause was jungler) up walks in, Blitzcrank with his passive shield(has 420 mana left) is up cause he was near death, Karma shielded(5pts) by herself walks in and Janna unshielded walks in. The item is activated and a shroud of fire(can be anything else but in Dream it was a shroud covering the champs in fire that was like burning the shields to nothingness) goes around the the shielded targets. Janna isn't burned because she had no shield up on herself. So the damage isn't actually True Damage as we know it cause it doesn't burn your HP so maybe it'll get a new name like Shield Damage or something like that. (Blitz Top, Naut Jg, Karma Mid, Xayah ADC, Janna Supp)

• Numbers for Shields:

  • Janna shield on Xayah is shielding for 240 + 57(70% AP) so in total, 282 HP. Items giving AP are Ardent Censer(Which gives 60 AP but it's 70% of it) 42 + 15 AP from Quints = 57.
  • Nautilus shield is shielding for 85 + 449 (17% maximum health) so in total, 534 HP. 325 + 350 + 450 = 1,125 Bonus HP + 1518 lvl 13 Base HP = 2643. Items are Cinderhulk, Knight's Vow & Spirit Visage.
  • Blitzcrank is shielding for 210 HP(50% of his current mana which is 420 Mana)
  • Karma is shielding for 170 + 117 (50% AP) so in total, 287 HP. 100 + 60 + 60 + 15 = 235 AP. Items giving AP are Morellonomicon, Ardent Censer & Needlessly Large Rod + 15 AP Quints.

• Janna is not shielded so she takes 0 Damage.

• Numbers for Ohmwrecker item:

The following numbers aren't set, I'm not a professional analyst of sorts I'm just an average player that just so happens to have a dream about this and is doing his best to express this idea the best way he can. I'm just giving some numbers that seem alright for me but with suggestions from the comments we could modify it so it seems more balanced :)

• The ACTIVE effect of the item will deal Shield Damage to all shields within its radius(650 radius maybe? or 800? whichever seems more balanced). The damage scales with level and are fixed numbers meaning they will not scale with AP, AD, HP or anything else(Making it this way means it cannot be abused by players to deal more damage).
• If it scales like 6/11/16 it would deal 100/200/300 Shield Damage
• if it scales like 4/8/12/16 it would deal 120/190/280/360 Shield Damage
• If it scales like 1-18 it would deal 100-500 Shield Damage. This scaling may be broken BUT most games don't usually last that long where every player is lvl 18 but if majority do then maybe 480 Shield Damage? Cause a level 18 AP Karma will have her E shielding for 491 HP. A level 18 Tank Nautilus will have his W shielding for approx 618 HP depending on items. If he has Stoneplate and activates it around 3 enemy champions then it would be a lot more.
• The cooldown on a item that causes a big impact if used right, has to be long. If it's too short it's easy to abuse it. So which option would be better
  1. 240 second cooldown
  2. 180 second cooldown
  3. 120 second cooldown
  4. It scales at levels 6/11/16, 240/160/120 second cooldown

I think that's all of it. I sure hope I didn't forget anything cause that was a lot of math I just did lol. I hope you like this idea thanks to the dream I had. Though I'm 100% sure it wouldn't have happened if I didn't read the original reddit post so thank you to /u/dariemf1998 for your post on Ohmwrecker
